摘　　要：对水布垭水利枢纽泄洪消能布置进行了整体水工模型试验,研究分析溢洪道入口、消能区及坝址下游水流特性,观测了窄缝挑坎挑流特性、消能区的冲淤情况和防淘墙的脉动压力和频率,从而解决了水布垭工程泄洪消能问题。A model experiment was carried out on the hydraulic structure layout of flood discharge and energy dissipation for the Shuibuya hydropower project. The characteristics of flow in the entrance of spillways, energy dissipation zone and downstream the dam toe were studied. Jet flow, scour and deposition in the energy dissipation zone as well as pulsation pressure and frequency against the anti-scour walls were measured and analyzed in order to solve the problems of flood discharge and energy dissipation for the Shuibuya Hydropower project.
